FOR FILES.

To aZZ whom it may concern.-

Beit known that I, WILLIAM H. KELL, a cit-izen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new'anduise'ful Iniprovementsin Binder-Bars for Files, of which the followingis a specification. V

The object of this invention is to provide a simple and easily-regulated'locking mechanism adapted to hold the contents of the file against displacement and capable of being easily unlocked and removed and allow access to the file for the purpose of adding thereto or subtracting therefrom.

A further object of this invention is to provide a mechanism which will lock and unlock both of the filing-pins simultaneously; and the invention consists in the features of construction of parts hereinafter described and claimed.

In thedrawings, Figure 1 is an end elevation of an ordinary letter-file, showing the binder-bar in position. Fig. 2 is a top or plan viewofaletter-file,partlybrokenaway. Fig. 3 is a bottom view of the binder-bar and mechanism therein contained in unlocked relation; Fig. 4, a similar view to Fig. 3, showing the parts of the bar in locked relation and the, protecting-blocks removed; and Fig. 5 a longitudinal sectional view of Fig. 3.

As shown, the locking-bar is arranged in position on a letter-file consisting of a stiff lower board or cover A and a, hinged upper fixed section a and a hinged section a, connected, by means of a hinge C6 in the usual manner, and between the upper and lower boards or covers are arranged the letters, orders, or other files to be preserved or filed. The locking -bar, which more particularly forms the subject-matter of this invention, is arranged to lie outside of and in longitudinal relation to the fixed section a of the upper cover and is composed of an upper plate, oblong in form, which may be made of metal or other suitable material and is provided with two holes Z) for. the passage therethrough of filing pins or studs B, which are fixedly attached to and extend upward from the lower board or cover through the letters, orders, or other files inserted between the covers and through the fixed section a of the upper board or cover and finally through the binder-bar. Fixedly attached to the under face of the plate are guide-blocks O and 0, two in number, as shown, and arranged adjacent to the holes I) in the upper plate. Each of these guideblocks is provided with two longitudinallyextending holes for the passage therethrough of locking-rods O, which are united together at one end by means of a head 0', the inner face of which when in unlocked relation is in alinement with the outer edge of the hole contiguous therewith, while the opposite ends of the rods are united by means of a cross-head D, into which the ends of the rods are inserted and held by means of pins d or otherwise. Slidably mounted on the two rods and normally in contact with the cross-head D, which unites the ends of thelocking-rods, is a sliding locking-block D, which is adapted to travel toward and from the hole in the plate and when advanced to the position shown in Fig. 4 to contact with the filing pin or stud inserted therein and by the pressure exerted against the filing pin or stud by means of the locking-block to unite or lock the bar against removal from the filing pins or studs. The cross-head D is provided withan interior screw-thread, and the lockingblock D is also provided with an interior screw-thread in opposite relation to the screwthread in the cross-head. Screw-threaded into and throughthe cross-head is an adjusting-screw E, which is provided with normal screw-threads e, which engage with the screwthreads in the cross-head, and is further provided on its inner end with oppositely-turned screw threads 6, which engage with the screw-threads in the locking-block, causing the locking-block and the cross-head to be oppositely moved as the adjustingscrew is turned, thereby drawing back the lockingrods and causing the space between the locking-block and the head connecting the two rods to be diminshed, by which means the locking-block andthe head are brought into tight contact with the two pins or studs and lock the entire bar against removal. The adjusting-screw is provided on its outer or free end with a squared head for the insertion thereon of a key for turning the adj neting-screw, and the end of the screw is held against lateral movement by means of a recessed guide-plate E, which is secured to the plate B by means of pins 6 or otherwise.

In order to protect the locking mechanism from injury either by bending or by the admission of dirt thereinto, protecting-blocks F, F, and F are inserted in the spaces between the guide-blocks, the blocks F and F being recessed to allow space for the operation of the locking mechanism and the block F preferably consisting of two sections, although a single recessed block would perform the same function. The blocks are of a thickness to lie flush with the lower faces of the guide-blocks O, c, and E.

In use the letters, orders, or files to be preserved are inserted in place on the filing-pins in the usual manner, and the uppercover is then brought down in place thereon, after which the pins are inserted through the holes in the locking-bar and the latter is firmly locked onto the pins by means of the movement of the adjusting-screw, as heretofore described. It will thus be seen that a single movement serves to lock the bar to both of the filing-pins, that the mechanism is simple and readily adjustable, and that the parts are so inclosed and protected as to be free from the danger of injury.

What I regard as new, and desire to secure by Letters Patent, is

1. In a lockingar, the combination of a plate having therein holes for the passage therethrough of filing-pins, locking-rods connect-ed at theirrearends and slidablymounted in relation to the plate, a locking-block slidably mounted on the rods, and means for simultaneously moving the rods and the block in opposite relation, substantially as described.

2. The combination of a plate having therein holes for the passage therethrough of filing-pins, locking-rods connected at their rear ends and slidably mounted in relation to the plates, a locking-block slidably mounted on the rods and provided with interior screwthreads, an adjusting-screw threaded into the locking-block, and means for holding the screw in coacting relation, substantially as described.

3. In a lockingbar, the combination of a plate having therein holes for the passage therethrough of filing-pins, guide-blocks attached to the under face of the plate, locking-rods connected at their rear ends and slidably mounted within the guide-blocks, a locking-block slidably mounted on the rods and provided with interior screw-threads, an adjusting-screw threaded into the lockingblock,and means for holding the screw in coacting relation, substantially as described.

4. In a locking-bar, the combination of a plate having therein holes for theadmission therethrough of filing-pins, an adjustingscrew provided with oppositely arranged screw-threads, locking-rods, slidably mounted and connected at their rear ends, a locking-block having therein a screw-thread and slidably mounted on the locking-rods, and a cross-head having interior screw-threads in opposite relation to the screw-threads in the locking-block and adapted to travel in opposite relation thereto upon the rotation of the adjusting-screw, substantially as described.

5. In a locking-bar, the combination of a plate having therein holes for the passage therethrough of filing-pins, parallel lockingrods united at one end and connected at their other ends by means of a cross-head having therein interior screw-threads, guide-blocks for the movement therethrough of the locking-rods, a locking-block slidably mounted on the locking-rods, and having interior screw-threads in opposite relation to the screw-threads in the cross-head, and an adjusting-screw having opposite screw-threads for engagement with the opposite screwthreads of the cross-head and the lockingblock, substantially as described.

6. In a locking-bar, the combination of a plate having therein holes for the passage therethrough of filing-pins, parallel lockingrods united at one end and connected at their other ends by means of a cross-head having therein interior screw-threads, guideblocks for the movement therethrough of the locking-rods, a locking-block slidably mounted on the locking-rods, and having interior screw-threads in opposite relation to the screw-threads in the cross-head, an adjusting-screw having opposite screw-threads for engagement with the opposite screw-threads of the cross-head and the locking-block, and protecting-blocks inserted between the guideblocks, substantially as described.
